Semantics of "loading" (ODF all versions)

Dear all,

2.13 had:

----b
Scripts must not modify a document while the document is loading.
However, scripts may recognize events immediately after a document is
loaded.
----e

What are the semantics of "loading" and "loaded" in ODF?

* Does this imply an ODF processor has to transfer an entire ODF
document into memory associated with an application process before
"loading" is complete, and at that point the document becomes "loaded". 

* Is an ODF processor/script then free to perform _any_ modification it
wants on that loaded resource? 

* Does this model preclude paged/streamed/shallow-loaded treatment of
ODF documents?

A loading model must be formally defined for these kinds of normative
statements to be meaningful.

Again, a formal terms and definitons section for ODF covering such
things may help to improve the overall document quality.
